Moving bed biofilm reactor
The AnoxKaldnes™ MBBR (Moving Bed Biofilm Reactor) technology is a biological wastewater treatment where an active biofilm grows on small specially designed plastic carriers that are kept suspended in the reactor. The microorganisms growing on the inert carriers are responsible for the removal of COD, BOC, ammonia and nitrogen from the wastewater.
AnoxKaldnes™ MBBR treatment is suitable for both industrial and municipal wastewater. It is mainly used in the following applications:
The AnoxKaldnes™ MBBR technology can be used in many different configurations. The technology can be fitted into different reactor shapes. Existing reactors (filters, RBC's and activated sludge plants) or other available vessels (pulp storage, oil tanks, and sludge storage tanks) have been used.
The carriers can also be added directly into the aeration lane of an existing activated sludge reactor to increase its organic loading capacity, and to an activated sludge plant with no nitrification due to too low sludge age.
Several different types of carriers have been developed in order to optimize their function in different applications. Media products include:
